When the sysref pulse is generated, the feedback from the register shows that the clock output phase is unstable, but the oscilloscope can catch the clock pulse, is this normal?

The level fed back through the GPO is always low, but the oscilloscope can capture pulses of a fixed period. 0x5a is set to 05, 0x5b is set to 05, 0x5c is set to 00, 0x5d is set to 04, 0x46 is set to 00, and 0x50 is set to 0f. Where could be the problem?
